Medical Diagnosis Exams

Chlamydiaceae species are gram-negative, small, nonmotile, obligate intracellular organisms that grow in the cytoplasm of host cells. The Chlamydiaceae family currently includes two genera of clinical importance, Chlamydia, which includes Chlamydia trachomatis, and Chlamydophila, which includes Chlamydophila pneumoniae and Chlamydophila psittaci.

Chlamydia trachomatis includes three human biovars and can cause a variety of infections in humans, eg. urethritis and cervicitis, trachoma, pelvic inflammatory disease, ectopic pregnancy, neonatal pneumonia, neonatal conjunctivitis, lymphogranuloma venereum.

Serology tests are used for the clinical diagnosis of chlamydial infections.
